MEANS FOR MAKING ARTIFICIAL PLATE-ICE.

aamc a.

To all whom it may concern:

Be it known that I, JOSEPH J. DE KINDER, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Means for Making Artificial Plate-Ice, of

which the following is a specification.

My invention relates to means to make at:

one and the same time a plurality of plates of artificial ice in a pure crystal-like state,

free from air bubbles or needles in' each lof a series of cans arranged in nested relationfirst, to )rovide practical means to produce a plurality of plates of artificial ice at one and the same time in each of a series of cans under the influence of a refrigerant, for instance, a brine solution such as ordinarily employed in artificial ice production; second,to provide means for producing a plurality of plates of ice in each of a series of cans With a device for agitating as well as sterilizing the body of wateramdergoing freezing into a plurality of plates of artificial ice and without ice films or ice bridges being formed between the built up ice into a plurality of plates of ice of each of the cans;,third, to provide economical and thoroughly practical means to permit of producing in each of .a series of cans at one and the same time from a body of water, a plurality of independent or distinct plates of artificial ice and in which during their formation they are insulated and isolated from one another by a hollow barrier and at the same time during their formations supplying ozone or air to the body of water of each can and while being congealed or frozen into plates" of artificial ice and with the formation of ice films or ice bridges prevented, during the formations into separately built up plates of such artificial ice; fourth, to provide econoiuical and practical means to permit of the quick thawing of the formed plates of ice in each can, without affecting other formations into plates" of ice oing on in other cans of the nested series of cans mounted in a refrigerating tank; fifth, to provide economical and practical means to permit of a plurality of plates of artificial ice being built Specification of Letters Patent.

up in each can atone and the same time and the therebetween water of the body of water Wllllfl being congealed or frozen into such plates of artificial ice thoroughly insulated andisolated and required agitations of the body of water permitted between the formin gplates while the freezing is going regularly onto thusassist in the preventing of ice films or bridges being built up bet-ween or "about the forming plates of artificial ice; sixth, to provide means to quickly and effectively thaw formed lates of artificial ice in each can, without disturbing other bodies of water being frozen into plates of artificial ice in other cans, when the cans are arranged in nested relationship within a refrigerating tank; and seventh, to provide a watercoutaiuingrefrigeratingcan internally arranged with a hollow barrier to isolate and to insulate the subdivided body of water of each can so that by freezing to provide two separate or distinct plates of artificial ice in each can, the said barrier also aiding in the thawing of theformed plates of artificial ice, as well as affording withdrawal .of uncongealed water from each can either before, duringonafter the thawing off of the plurality of plates of artificial ice of the series in nested relationship within a refrigerating v tank.

Figure l, is a top or plan view of a refrig crating tank provided with a series of separated cans for forming in each a plurality of plates of artificial ice, also showing the wooden or other insulating partitions forming the tank into a series of sections, the hol low barrier of each can for insulating andisolating a body of fluid of each can while being congealed or frozen into separate plates of ice, the controlled freezing medium a to be supplied about each can of theseries of the tank and arranged so astobe shifted from one side of a can totheother, to maintain thereby the fluid bodybeing frozen, uniform, the means for discharging the freezing medium from the tank and piping beneath the tank with-suitable connections to the tank about the cans for thawing or loosening the ice cakes of each of the series of cans; and Fig. 2, is a vertical sectional view on the line as, m, of Fig. 1, showin the general internalldetail arrangement 0 the series of nested cans within insulated sepa-' rated sections of a refrigerating tank.

Referring to the drawings A, is an oblong metal or other type of can. This can is provided interiorly thereof, with a barrier B, which as shown is in form hollow and of a U-shape, in structure to insulate and isolate a bodyof water placed in a can to be congealed or frozen into artificial plate ice, when a freezing medium, such as a brine solution, is brought exteriorly in contact with the bottom and walls of the can, for example, either by immersion of the fluid containin can A, in a refrigerant tank or in any ot er preferred {manner suitable for artificial ice makin The hollow barrier B, in use, serves to su ciently insulate and isolate the volume of water within the can, during the ice formations from the bottom and walls of each can toward the barrier and so as to economically and practically, sub-divide each can in order to permit in the congealing of such body of water two separate or distinct plates of artificial ice at one and the same time being produced. Moreover, the barrier B, provides a means in which a heating medium may be conducted therethrough to assist in the thawing or loosening of the built up plates of ice and thus removal of the plurality of plates of ice formed in each can. This barrier B, as arranged in Figs. 1 and 2, servesas a support for a perforated device C, for admittmg an agitating fluid, as ozone or air from a supply, not shown, through a vertical pipe 0 or 0 connected with the device, so as to pass from the perforated device C, in a bubbling or streamng form either continually or intermittently into the body of water of the can and while the freezin of the said body of water is going on to orm a plurality of plates of ice therein, in a sterihzed state in the one instance or purified lates of ice, in the other. The admitting of the agitating fl id as ozone or air into the body of water a1d in preventing ice films or ice bridges being formed between and aboutthe barrier B, sub-dividing the body of water of each can.

ing'intoeach section a heatingmedium forloosening the "ice cakes formed. 12, is' the brine supply pipe, which b branch pipes ll", connected w1th the series of sections d, of the tank D, supply a solution around the cans A, by means of piping d, arranged to be swung either to one side or to the other of the cans A, of the series of sections d, of the tank D. Each branch, ipe d, is provided with a stop-cock d", for s utting off the brine supply.

d, is a brine discharge pi e from each of the sections d, of the tank 1% to a receiving vat, not shown, by T-connections d, provided with stop-cocks d, whereby the discharge of brine is under perfect control. The terminals of the connections (1", within the sections d, of the tank D, may be arranged so as to receive detachable standpi s d and d", to facilitate removal of the re igerant from the sections (1, throu h either the ipe d, or the pipe d", into t e discharge The ipe d, or the pi d", not in service, may he plugged up, if t e arrangement as shown is used as a means to free a section d, of the tank D, of its brine solution, after a pluralityof lates of artificial ice have been formed. T awin of the plates from the bottom and walls of t e cans A andaway from the hollow barriers B, when the sections are deprived of their brine solution, is permitted by passing a heating medium from a supply through the pipin d, andnipples d, into the bottom of eat: of the sections d, of the tank D, and to a height sufiicient to accomplish the desired thawing of the plates of ice formed from the bottom and walls of the cans, within the tank D. At the same time, a hose may be directed through one of the legs or members b, b, of the hollow barrier B, if desired, to facilitate the thawing o eration.

It will be understoo that loosening of the ice cakes of one can may be quickly accomplished and while other fluid-contained cans of the series of the tank D, are each making a plurality of cakes of ice. With the sections at, of the tank D, arranged so that the brine supply can be quickly reversedto admit the brine either to one side of the can or to the other of each section, if one portion is colder than the other, this'is quickly corrected thereby, so as to insure uniformitty in the formation of the plurality of cakes 0 ice in a given time in each'of the cans.

Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is In an ice making machine, a refri erating tank divided into a series of independent sections to support cans, means to permit of a lurality of plates or cakes of artificial ice oing made at one and'the same time in said cans, piping connected with said tank to conduct the heating medium into the sections of the said tank for loosening the ice cakes In witness whereof, I have hereunto set or plates of stud cans and a brme supply my signature 1n the presence of two subscrih- 10 having branches leading to said tank for mg witnesses. conducting the brine around said cans and w 1 1 r 5 having extensions arranged to be swung from JOSEPH JAMES E one slde to the other of the cans of said \Vitnesses: tank, substantially as and for the purposes, J.
